Question

State the properties and uses of a Junction Diode.

Answer 1

Properties:

The p–n junction possesses some interesting properties that have useful applications in modern electronics.

A p-doped semiconductor is relatively conductive. The same is true of an n-doped semiconductor, but the junction between them can become depleted of charge carriers, and hence non-conductive, depending on the relative voltages of the two semiconductor regions. By manipulating this non-conductive layer, p–n junctions are commonly used as diodes: circuit elements that allow a flow of electricity in one direction but not in the other (opposite) direction. Bias is the application of a voltage across a p–n junction; forward bias is in the direction of easy current flow, and reverse bias is in the direction of little or no current flow.

Uses:

1.)It is in the process of rectifier as one of the part of DC Power Supplies.

2.)Detector Circuits.

3.)In bracing systems utilized as DC Restorers.

4.)In cut-out circuits utilized for waveform era.

5.)Switches in advanced rationale circuits.
